PATENTJOFFICE ARTHUR D. GALLAGHER, orv CANTON, ILLINOIS, ssIGNOR, BY MEsNEas'sIGNMENTs, To FRED GERLAOH AND ARNOLD B. KELLER, TRUsTnEs-BOTH on CHICAGO, ILLINOIS Two WAY TRACTOR PLOW i Appnanon mea March 14,

This invention relates to tractor pulled plows of the two-way or hillsidetype.

The main object of theinvention is to provide a simpliied form of carrying frame and 5. lifting mechanism for plows of thev type stated and to construct` and arrange the two lat-4 eral halvesfoie themachine and the` plows carried side by side thereon, so as to attain automatic leveling of the operating plow with one of the 'carrying wheels running in the furrow, vwithout employementxof adjustable carrying wheelsas heretofore done.

Another object is to provide. a novel sus- Ypensiontype of supportingand lift mechanismV for each plow beam, which will permit of easy adjustment for depth and tilt of the respective plows and `provide a high ground clearance for the idle plow during operation of the machine. i

Still anotherobject is to provide simple mechanism `for actuating the .respective beam lifts by tractor power.- f

Other objects and advantages will become apparent from the `detailed description hereinafterl given of the organization and'details of construction embodying the invention.

In the accompanying drawings: f

Figure 1 is a plan view'of al two-way plow embodying the invention; I

Figure 2 is a side elevation of the same;

Figure 3is a rear view: y

Figure 4 is an enlarged detail view of the adjustable Vfront connection for each plow beam; and, v

Figure 5 is a detail view of a part used in the adjustable connection shownin Figure In each of the iirst three figures above described. the parts are shown in the position assumed when the right hand plow is in lowered or operating position and the'left hand plow in raised. or'idle position.

In the present instance, the invention is illustrated as embodied in a plowv structure comprising a main frame of onen formation and comprising a horizontal. forwardly extending arched portion and a rear. upwardlv arched portion. Vln the present instance this frame is shown as consisting of side bars formed with upwardlv angular extensions 11 i at'their rear ends, which are connectedby a 1930; serial No. 435,713.

transverse vcylindrical bar 12 forming the bight portion of the upwardly extending rear arch.v The forward ends of the side bars 10 ofthe frame are rigidly connected as by a transverse yoke member 13. At the angle or junction between the horizontal and vertical portions of the .side bars l0, each outer side of the frame has secured thereto a bearing bracket 14. A spreader bar 15 extends across the frame and is rigidly secured to the respective bearing brackets 14v as by U-bolts 16. The bearing brackets 14 are'provided with transverse bearings and the 'brackets are so connected to the frame asto dispose the bearings and the respective brackets on axes 'converging upwardly at angles of about 10 from horizontal towards the central `longitudinal vertical plane of themachine, vas best seen in Figure 3. Each of the bearing brackets has j ournaled therein a' stub axle `17, which projects outwardly beyond the bracket andhas journaled thereon a supportingwheel 18, thehub of which has integrally formedv therewith one member1o19 of anintermittent clutch mecha- 'nism of the half revolution type. At the inner end of each stub axlethere is provided a crank arm 20.V A central, longitudinal bar or brace 21 connects the mid-portion of the spreader bar 15 `with the forward end of the 80 4 At the forward end of the plow frame two transversely extending, cylindrical draft bars 22 are provided. These converge upwardly towards the center line of theframe at substantially the same angle'as the stub axles 17 and bearing brackets 14 and are secured to the central bar 21. Each one of the bars 22 has set bolts or screws 26will serve tovadjust the beamihead about the .bolt 28 as ani axis, while4 both the beam head and yoke member 23 may pivot on the bar 22. As best seen inFigure l, each'angularly V bent bar 27` forinsa-coup.A ling member for a rearwardly extending plow beam 29 carrying the usual plow body 30 at its rear end. It will be understood that the structure described-is duplicated at each side,

thus providing a pairY of oppositely facingplow bodies for alternate Vuse as'nsual 1in Atwo-y e.:
